I have an iphone 2G running 3.12 that was customized with pwnagetool (unlocked & jailbroken). I am using a pay as you go plan so I only have data in wifi. The phone works great around the house but when I go out it starts to error. The apps stop working and an error pops up saying the phone needs to be restored. Some times it even goes offline and will no longer make or receive calls. I can then restore it with the same firmware and it will be fine for a day or two. Originally I tried to unlock it with black rain before I realized that I needed bootneuter. My guess is that I screwed up the baseband and it bombs when it tries to access cellular (edge) data.

Has any one seen this before? Any reccomendations would be appreciated.
